These games, which are designed for screening and training purposes, are played on a hexagonal (honeycomb) pattern board. The games are of the 2- person type with incomplete information, Each player has a board marked off into hexagonal fields, and there is a barrier which can be placed between the boards when secrecy is desired. Each board is divided into a home territory and an enemy territory with a no man's land between. Disks of various colors are used as markers for the fighting units and cities. At the beginning of a game the number of fighting units is roughly 10 times the number of cities. The object of the game is to kill all the units of the opponent. The equipment and rules have been kept simple so that the games are inexpensive and easily learned. Some of the games are unfair in the sense that 1 player has a definite advantage. In others the players operate under nonsymmetric conditions. The purpose of this variability is to test adaptability. Some games require boldness and others caution. The terms used to describe the play are military, and an effort was made to make the situations as realistic as possible within the bounds set by the requirement of simplicity.
